Hello ,, i have a loose bowel for a week now not diarrhea and only once a day what its the cause is it food or something else?

See below: Diarrhea describes bowel movements (stools) that are loose and watery. It is very common and usually not serious. Many people will have diarrhea once or twice each year. It typically lasts two to three days and can be treated with over-the-counter (OTC) medicines. If you have loose stools longer than few days, please see PCP to determine etiology.
